Motorola V600
Perhaps a better phone?

Also, this phone has 850 band coverage which the Sony Z600 does not have and is need for AT&T use.
Also, I've been using a SE Z600 on the ATTWS network in DC SEAMLESSLY for a month now: super RF/signal (contrary to what everyone says!), mMode configured easily and never better, perfect with my HBH-65 BT headset, etc. etc.
